Patented June'l, 1909.

Application filed March 20, 1909. ,Zserial No. 484,821.

To all whom it may concern:

Be it known that I, MILO L. DECKER, a citizen of the United States,residing at Maxwell, in the county of Lincoln and State of Nebraska,have invented certain new and useful Improvements in Hut-Locks; and I dohereby declare the following to be a full, clear, and exact descri tionof the invention, such as will enable others skilled in the art. towhich it appertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part I of this specification. 15

This invention relates to new and useful improvements in nut locks andcom rises various details of construction, com inations and arrangementsof parts which will be hereinafter fully described and then specificallydefined in the appended claim.

My invention is illustrated in the accom panying drawings, in whichFigure ,1 is a perspective view of the in- 7 vention showing a lockapplied to a nut upon showing the lock applied a series of groovesgrooves in the bolt.

a bolt. Fig. 2 is a detail of one end of the bolt. Fig. 3 is an'enlargedperspective view to the nut, and Fig. 4 is a sectional view. Fig. 5 isan end view of the nut and pawl mounted thereon.

Reference now being had to the details of the drawings by letter, Adesignates a headed bolt having a threaded portion with B formedlongitudinally. therein, and D designates a nut mounted upon thethreaded portion of nut having a threaded bore as usual and a Fdesignates a pawl having a laterally rojecting lug E which is adapted toswing into said recess and a portion of said lug pro jects within thebore of the nut and is adapted to engage one or another of: the Saidpawl is pivotally connected to one end. of the spring G which in turn isfastened to one end of the nut and the bolt, said said spring is adaptedto hold the pawl frictionally and serves to retain locked relation afterthe latter is swung into a groove.

In applying the nut, it is fitted upon the threaded portion of tire boltin the usual manner and, when it is desired to lock the nut, the pawl isswung upon its pivot so that the laterally projecting portion of the lugthereon will engage a groove in the bolt. The spring beers withsufficient frictional force against the pawl to hold the same in itslocked relation. A knob or headed in K projects from the free end of thepaw and aii'ords means for throwing the same in one direction or theother as ma be desired;

From the foregoing, it wil be noted that by the provision of a nut lookas shown and.

described a simple and efficient means is aiiorded 'whereby'a nut may besecurely held from loosening when adjusted upon a bolt and so arrangedthat the nut maybe easily and uickly removed when desired.

What 1c aim to be new is 1- A nut lock comprising a bolt having athreaded portion with grooves formed longitudinally therein andtransversely across said threaded portion, a threaded nut fitted to saidbelt, a spring fastened at one end to the end of said nut, a curved pawlpivotally the pawl in a connected to said spring and adapted to be heldby the latter Emotionally against the end of the nut, a lug projectingfrom the inner concaved edge of said pawl and extending laterally andadapted to engage one or another of the grooves in the bolt, and a knobupon the free swinging end of said pawl, as shown and described.

In testunony whereof, I hereunto aflix my signature 1n the presence oftwo witnesses.
